NSW man traded drugs for gun before death

A Sydney man allegedly murdered by four so-called Blood Brothers traded the drug ice for a shotgun to protect himself from the group, a jury has been told.

Jamie Michael Tilley, 36, and Jack Davies, William Patrick Thomas and Mitchell James Bentley, all aged 27, have pleaded not guilty to kidnapping and murdering Brendan Vollmost, 23, at South Windsor in March 2015.

Giving evidence at the NSW Supreme Court on Friday, Ronald Byrnes said before his disappearance, Mr Vollmost told him a shotgun in his shed was to protect him from the Blood Brothers.
